WebHaeckel portrays a concrete demonstration of his Biogenetic Law through his Gastrea theory, in which he argues that the early cup-shaped gastrula stage of development is a universal feature of multi-celled animals. An ancestral form existed, known as the gastrea, which was a common ancestor to the corresponding gastrula. [12] WebErnst Haeckel addressed the issue with his Biogenetic Law, and his embryo drawings functioned as supporting data.
